Palladium-catalyzed desulfitative Sonogashira-Hagihara cross-couplings of arenesulfonyl chlorides and terminal alkynes

For the first time, conditions have been found for the palladium-catalyzed desulfitative carbon-carbon cross-coupling of arenesulfonyl chlorides with aryl- and alkylacetylenes. Pd-2(dba)(3)/P(t-Bu)(3) and CuI provide the best catalyst for reactions in re-fluxing THF and in the presence of K2CO3.
